Bouncer's Beatdown

The cost reduction is doing something sneaky: fight-style green removal has always paid its way through the creature you already control, but here the discount is keyed to the target's color rather than yours. Point it at a black permanent and the price drops to a single green mana, turning what looks like a midrange trick into a color-hosing efficiency spike. That is a deliberate lever, a green removal spell priced to punish black specifically, and it says something about how designers tune a fixed-cost effect against the metagame they expect it to answer. Note the crucial mechanical detail: the spell itself is the source of the damage, with X read off the greatest power among your creatures. That distinction separates this from a true bite effect, because the damage never inherits deathtouch, lifelink, or any other combat keyword your big creature happens to carry; the board only sets the number. Whatever the damage does kill gets banished rather than dying, shutting down reanimator fodder, recurring threats, and death triggers that would otherwise cash in, and that clause fires whenever the creature or planeswalker actually would die this turn, so a body that survives X but dies later that turn is still exiled. Green rarely gets clean answers to planeswalkers, and aiming board-scaled damage at a walker while foreclosing any graveyard return quietly fills part of that gap. The catch is the one every power-based removal spell carries: an empty board or a lineup of small creatures leaves X low or zero, and the discount only matters when your target happens to be black.
